Struct template reverse_fold

boost::proto::reverse_fold — A PrimitiveTransform that is the same as the proto::fold<> transform, except that it folds back-to-front instead of front-to-back. It uses the proto::_reverse callable PolymorphicFunctionObject to create a fusion::reverse_view<> of the sequence before invoking fusion::fold<>.

Synopsis

// In header: <boost/proto/transform/fold.hpp>

template<typename Sequence, typename State0, typename Fun> 
struct reverse_fold :  proto::fold< proto::_reverse(Sequence), State0, Fun > {
};
